Description Marian Rehak 2021-07-12 14:30:33 UTC 
When curl is instructed to download content using the metalink feature, the contents is verified against a hash provided in the metalink XML file. There's a risk the user doesn't notice the message and instead assumes the file is fine.
Comment 1 Marian Rehak 2021-07-12 14:35:11 UTC 
This flaw has existed in curl since commit [b5fdbe848bc3d](https://github.com/curl/curl/commit/b5fdbe848bc3d) in curl 7.27.0, released on July 27, 2012.
